Using the police reports and autopsy of Darlene Ferrin we can reconstruct the mechanics of the crime scene at Blue Rock Springs Park on July 4th 1969. Michael Mageau was struck four times and survived, but Darlene Ferrin received nine entry wounds and seven exit wounds from five direct hits. The police recovered nine shell casings from the crime scene, seven to the right side of the brown Corvair and two on the floorboard of the rear passenger area. The diagrams below will show the possible order of events that night, followed by a more detailed examination.

[1] and [2] The widely held belief is that Michael Mageau was targeted first during the initial barrage of gunfire, but the autopsy report of Darlene Ferrin may suggest otherwise. The young woman received 4 entry and 4 exit wounds to both arms, indicating that she may have had both arms on the steering wheel when the first bullet was discharged. Each bullet entered the right arm and exited, before striking the left arm and exiting, creating the 4 entry and exit wounds described at autopsy. If the killer had targeted Michael Mageau first, it is extremely unlikely that Darlene Ferrin's first reaction would have been to turn the key in the ignition and place her hands on the steering wheel in an attempt to pull away. There simply would not have been enough time to achieve such a feat, not withstanding the fact, that the natural reaction after seeing Michael Mageau shot, would have been to turn away from the direction of fire. Had this been the case, the wound pattern to the arms of Darlene Ferrin would be harder to explain. The killer fired off the first two shots into the vehicle, firstly striking Darlene Ferrin just above the right wrist as she was gripping the steering wheel. Her right arm came across her upper body towards her face (either manually or by the resultant force), as the second bullet entered her right upper arm 5 1/2 inches above the elbow on the lateral side, exiting and striking her left upper arm 3 1/4 inches above the elbow. [3] and [4] When the killer opened fire on Darlene Ferrin, Michael Mageau turned away, lowering his body from the barrel of the gun. After the initial two shots, the killer then turned the gun on Michael. He was struck twice, once in the neck (facial area) and once in the shoulder, before propelling himself to the rear of the vehicle in an attempt to escape the barrage. Both of these bullets exited his body, striking Darlene Ferrin in the torso. The two bullets lost momentum after passing through Mageau and had reduced velocity when they entered Darlene Ferrin, thereby remaining in her body. #1 was removed from the right second rib. #2 was removed from the seventh and eighth rib left. These were the only two bullets recovered from Darlene Ferrin at autopsy. A letter was received by the San Francisco Examiner on July 4th 1969 in which Zodiac described his attack "On the 4th of July I did not open the car door. The window was rolled down all ready. The boy was origionaly sitting in the front seat when I began fireing. When I fired the first shot at his head, he leaped backwards at the same time, thus spoiling my aim. He ended up on the back seat then the floor in back thashing out very violently with his legs; that's how I shot him in the knee." Michael described these two shots in the police report: "He heard a muffled sound and felt a pain in his back and his neck area. He states he heard some more muffled sounds, sounding like a gun with a silencer on it, and felt pains in his body, his back and around his neck. States he tried to climb over the back seat to get away from the shooting." Thekiller had now fired 4 shots. Michael Mageau had been struck twice, and Darlene Ferrin had received 6 entry wounds and 4 exit wounds.

[5] After Michael Mageau had found temporary refuge in the rear of the Corvair, the Zodiac Killer fired the fifth shot into Darlene Ferrin's torso. The bullet exited her body. She now had 7 entry wounds and 5 exit wounds. The killer then retreated according to Michael Mageau. But this was to be a brief respite.[6] and [7] The Zodiac Killer returned to the passenger side window and leaned into the vehicle, and extended his arm over the front seats to fire 2 more shots at Michael Mageau, striking him in the thigh and hip. These two expended casings fell onto the rear floorboard. The Zodiac described this as "he ended up on the back seat then the floor in back thashing out very violently with his legs; that's how I shot him in the knee."[8] and [9] The killer then turned back to Darlene Ferrin, firing off the final 2 shots. Both of these bullets struck her torso and exited on through. She had now received a devastating 9 entry wounds and 7 exit wounds, as described in the autopsy.Two of the final four shots were likely aimed at Michael Mageau first, as he explained to officers that he "could not tell if he meant to yell at the subject or if he just yelled from pain, but he let out some type of yell. At this time, the subject apparently hearing him, came back to the car and shot Michael two more times, once in the back and once in the left leg. States the subject then turned the gun on Dea and shot her twice more." Michael Mageau had actually been struck in the thigh and hip.The killer then retreated into the night. Just under 40 minutes later, the Zodiac would announce himself to the world in a chilling phone call to police dispatcher Nancy Slover.

Here is a depiction of the entry wounds (black circles) and exit wounds (red circles) to the arms of Darlene Ferrin.​The first shot traveled as shown, creating 2 entry and exit wounds. The second shot is more difficult to explain.​In order to make any sense of this wound pattern, imagine that we need to make these four circles approximately line up.The white arrow would depict how Darlene Ferrin's arm came across her body, placing it at extremely acute angle to the shooter (the act of turning away). The four circles are now lined up, producing 2 entry and exit wounds. The bullet entered 5 1/2 inches above the right elbow and exited 1 1/4 inches distal to the right elbow. It then entered 3 1/4 inches above the left elbow and exited the opposite side.The first shot didn't necessarily strike Darlene Ferrin while she was holding the steering wheel, but it is a strong possibility. The right forearm was struck 3 1/2 inches above the wrist, entering the left forearm 2 inches above the wrist.This however, is only one possible explanation. If you have any comments regarding this analysis, please let me know.

Extremely well laid out,Richard...in what is a difficult sequence of ''bullet'' events to work out.

I shall read your article,a couple more times.....but as a general view .....

What is seemingly so apparent is,that this is an attack,by Zodiac on Darlene.....with Mike representing an ''inconvenience'' that needed to be dealt with,in between Zodiac's ''anger'' and focus on Darlene.

In the words of Dylan Thomas : ''Rage,rage,rage......''.

I can only say The Zodiac was either an extremely poor shot, or he wanted to make his victims suffer before he finally killed them.

If Z wore corrective glasses, then bad eyesight puts him in another category. He couldnt have been a mob hitman if he wasnt a real good marksman.

Z has been labeled a snitch, under a witness protection program, which explained the ability to move about freely with impunity. Did his damaged vision force a career change?? With a limp and poor eyesight, he might have collected a disability check which would allow more free time for people hunting as well.

Either way, without good eyes, he felt like he had to do a 'coup de gras' shot with David Faraday and Paul Stine. Did diminishing eyesight end his weekend slave hunting hobby and force him to move out of the Bay Area after Stine?

Zodiac's perceived physical disadvantages,do tend to persuade that he would not have passed a medical,for the military.

And,is it likely that he would have the energy,or inclination,to pursue a ''one man army'' campaign of terror,against the establishment and general public....in his time off,from the military [?].

From all accounts,the military were very helpful,in assisting law enforcement,in their efforts to track down this criminal.Their records of accountability for movements of their men,would have been quite keen and accurate.

Time to put the ''military angle'' to bed,once and for all [?].
